The CremaTTe® algorithm was developed by Analog Way to perform a high quality keying. If your live source
contains some transparent area or if you need to key a dicult video of people with wispy hair, you need to
use CremaTTe® algorithm.
Using the CremaTTe® algorithm, we advise you to start by using the keying assistant.
1. Start to remove the main color using the white square in the keying assistant.
2. Remember that you can freeze the source, and that you can add several areas by simply clicking several
me on ADD AREA buon.
3. Aer some iteraon, most of colors are deleted, enable the RED & BLUE mask to help you nd any missed
garbage on the screen.
4. At this point, with the mask enabled, you should have only RED & BLUE pixels on your live image.
5.  the edge smoothing sengs allow you to determinate some area where you want to
add transparency. Adjusng the H S L values will display some GREY pixels around the edge of your live
content. Those GREY pixels will later be rendered semi-transparent.
6. Adjust accurately the HSL in order to make transparent only the desired area. (A too high level will make
transparent some solid area).
7. At this point, disable the mask and return to you original live image.
8. You can see that some area sll have some color reecons. This can occur mainly on clothes and hairs.
Adjust the COLOR CORRECTION RATIO using the Hue and Saturaon sengs to nd the best result. Be
careful of the color correcon, a wrong seng can modify badly the color of skin. Try to nd the best com-
promise between color modicaons and reect areas deleted.
